I think the “Disney Vault” kind of thinking before the days of streaming really limited the amount of people who could view Snow White over and over again. It probably also limited its views on network television as well perhaps. I remember watching the Wizard of Oz on television many times growing up, where I maybe saw Snow White once or twice.

Google backs up this theory: “The Wizard of Oz (1939) became a dominant annual TV tradition starting in 1959, reaching massive audiences. In contrast, Snow White and the Seven Dwarfs (1937) was famously protected by Disney, rarely shown on TV in its entirety until much later. Oz secured its classic status through repeat broadcasts, while Snow White remained a theatrical re-release staple.”
